Hyper-Realistic Chiaroscuro Portrait

Create a hyper-realistic 8K cinematic portrait of the uploaded person in a {argument name="lighting style" default="dramatic chiaroscuro style"}. The subject is seated at a three-quarter angle, leaning slightly forward with a relaxed yet commanding posture. His face is turned slightly away from the camera,not looking at the lens, with one side of the face sharply illuminated and the opposite side fading into deep, velvety black shadow. His expression is contemplative. His hands are near the chest in a natural, precise pose, with the fingers gently and correctly interlocked. One wrist clearly shows a {argument name="watch" default="luxury black chronograph watch"} with a detailed metal link bracelet, and one hand wears a subtle silver ring. He is dressed in a {argument name="suit" default="sharp black suit jacket over a white dress shirt"} with the top buttons open, showing refined fabric texture and natural folds. The background is solid seamless black. Use strong directional studio lighting with rich contrast, clean shadow falloff, and realistic skin texture. Highlight fine details such as hair strands, beard(if present) bristles, eye moisture, facial texture, the watch face, metal bracelet reflections, and the silver ring. Shot with an 85mm portrait lens look, shallow depth of field, premium commercial photography, ultra-sharp focus, smooth natural skin transitions, cinematic contrast, no artificial plastic skin, no extra fingers, no distorted hands, no messy anatomy.
